4.2 – Common Faults
Below are some common faults. Accompanying each one is a list of the most common solutions. While the lists of solutions
are not exhaustive, they represent the majority of the likely failures.
The MatchBox does not show up on the PC.
o Check power is supplied and the power light is on.
o Check the MatchBox is correctly connected to the PC with a USB cable.
o Check the MatchBox is not connected via a USB hub as this may cause problems. If it does use a hub, try plugging
the MatchBox into the PC directly.
o Ensure the PC is running Windows 98SE or later (Windows 98 is not suitable).
The MatchBox appears to constantly reset.
The MatchBox must have a working Ethernet and a working USB connection in order to operate correctly. It monitors both
connections to ensure they are working correctly and if either connection is not working, the MatchBox will reset itself to try
and establish a working connection.
o Check the MatchBox USB port is correctly connected to the PC with a USB cable.
o Check the MatchBox is not connected via a USB hub as this may cause problems. If it does use a hub, try plugging
the MatchBox into the PC directly.
o Check the MatchBox Ethernet port is correctly connected to another CobraNet device or Ethernet switch.
o If connected to a switch, check the link status light to ensure a good connection.
The MatchBox is detected as a MatchBox 1x8 instead of a standard MatchBox
o Control Center is unable to distinguish between the two different MatchBox configurations because the MatchBox
has an older version of firmware. In order that all options can be set, Control Center defaults the MatchBox 1x8.
The connected MatchBox can still be set up by selecting the number of channels needed for outputs rather than
the number of devices.
*Note: Though the 2 channels out /6 channels in option is selectable, it will not work on the standard MatchBox as
this mode is not supported.
*Note: A firmware update is available if needed.
